I put a hand full of dirt in drinking water that was 6ph then i mixed well let the dirt settle and tested it... the good thing is my plants are doing much better bad thing is the home depot here doesn't have the on down powder or lime, they have some shit for pools to make the water ph go down will that work? if not my resolve is to let the plants do there own thing and not feed them anything but water, no nutes, or only best once a week but make sure there food is at 6ph or less what's ur opinion???
